[Technical field to which the invention belongs]
The present invention relates to a rear luggage compartment structure of a vehicle.
[0002]
[Prior art]
As is well known, a vehicle such as a passenger car is often provided with a luggage compartment having an opening opened rearward at the rear of the vehicle body, and a rear hatch or a trunk lid is used to open and close the cargo compartment opening. A so-called opening / closing body is provided. When loading / unloading (storing or taking out), the opening / closing body is displaced upward (in many cases, pivoted upward) to open the luggage compartment opening, and then load / unload the luggage. It has become.
[0003]
In the case of taking out a baggage from the luggage compartment at the rear of the vehicle body, it is desirable that the cargo compartment opening is as wide as possible and the lower end position thereof is as low as possible. In particular, if the lower end position of the luggage compartment opening is flush with the cargo compartment floor, it is very easy to load and unload luggage.
[0004]
In addition, a vehicle is known in which a circular recess having a contour suitable for wheels is formed on the cargo floor and a spare tire is accommodated in the circular recess. It is necessary to lift the spare tire from the circular recess. In this regard, if the rear end of the circular recess is open rearward, the user can remove the spare tire from the luggage compartment simply by pulling it backward.

[Patent Document 2]
Japanese Patent Laid-Open No. 8-175184
Japanese Laid-Open Patent Publication No. 8-175184 proposes that the entire rear bumper is attached substantially integrally to the lower end side of the opening / closing body of the rear cargo compartment, and when the opening / closing body is opened, the entire rear bumper is also lifted simultaneously. ing.
[0009]
[Problems to be solved by the invention]
When the method disclosed in U.S. Pat.No. 2,767,896 is adopted, when the luggage compartment is opened and closed by opening the lower opening / closing body of the luggage compartment, the lower opening / closing body is opened almost horizontally. Since it is necessary to secure the rotation space, it is practically impossible to greatly enlarge the luggage compartment opening downward in design.
[0010]
Further, in order to expand the cargo compartment opening downward, it is necessary to cut out an end panel disposed at the rear end of the vehicle body, and it cannot be denied that the rigidity of the rear end of the vehicle body is lowered. In order to cope with this, for example, as disclosed in Japanese Patent Application Laid-Open No. 8-175184, when a reinforcing member extending in the vehicle width direction is arranged in the rear hatch and the rear hatch is closed, the reinforcing member built in the rear hatch is used for the vehicle body. Although it is conceivable to ensure the rigidity of the rear end, there is a certain limit in securing the rigidity of the rear part of the vehicle body because the reinforcing member is not fixed to the vehicle body frame.
[0011]
A main object of the invention is to provide a rear luggage compartment structure of a vehicle that is convenient for loading and unloading luggage through a cargo compartment opening while maintaining rigidity of a rear portion of a vehicle body.
[0012]
A further object of the present invention is to provide a rear cargo compartment structure of a vehicle that can suppress the influence on the cargo compartment due to a collision from the rear, in addition to the main object.
[0013]
Another object of the present invention is to provide a rear luggage compartment structure of a vehicle that can easily put in and take out a spare tire accommodated in a cargo compartment floor.
[0014]

Therefore, the luggage can be divided and accommodated in the luggage compartment 2. For example, when the spare tire is stored in the second recess 17 which is the underfloor storage portion as in the embodiment, when the spare tire is taken out from the underfloor storage recess 17, it is simply lifted without being lifted. The spare tire can be taken out of the undercarriage storage recess 17 by simply pulling it out, so that the tire can be easily taken in and out. The same applies to the upper floor 11.
[0043]
In addition, since the under floor storage recess 17 below the reinforcing member 4a is opened and closed by displacing the bumper face 21 up and down, a part of the bumper face 21 is opened to open the under floor storage recess 17. It is no longer necessary to design the vehicle body so that the cut-out shape is filled with the lower end portion of the rear hatch, and the parting line that appears on the appearance when such a method is adopted is the bumper face 21. Therefore, the appearance of the rear part of the vehicle can be improved.
[0044]
Further, it is preferable to arrange the bumper reinforcement 21 at the same height level as that of the reinforcing member 4a that extends in the vehicle width direction and is fixed to the side frame 20, and just behind it. As a result, the impact force applied to the bumper reinforcement 21 due to a rear-end collision or the like from the rear can be released to the rear side frame 20 including the reinforcing member 4a, so that the influence on the vehicle compartment including the luggage compartment 2 is suppressed. be able to.
